1316864 - Google Apps extremely slow -- scrolling, updating text, etc -- unusable

Status: NEW

(Core :: JavaScript Engine, defect, P5)

Description

[George Roter]

When: About the past week

What:
All window scrolling, entering text, manipulating objects is extremely slow (noticeable delay) in Google Docs, Spreadsheet, Presentations and Gmail.

This is both in new/fresh documents and larger ones for all docs. It's for scrolling, entering text, deleting email.

This is with a small number of tabs open (or lots of tabs).

Also, I'm seeing the "spinner" when I switch tabs.

Comment 1

[Olli Pettay [:smaug][[e-mail]]]

So, this is a regression? If so, regression range please?

Have you restarted the browser? (just wondering if there is a leak)
Do you have addons? Have you tried with a fresh profile? ...the usual checks.

Comment 2

[George Roter]

Sorry I knew I forgot something.

I did a "Refresh" 2 days ago, with no change. No addons.

Regression range: Can you explain a bit more what info I should give you? Timeframe? I started noticing this last week, but it got really unusable this week. 

Is there a way to look at dates when the browser updated?

Comment 3

[Olli Pettay [:smaug][[e-mail]]]

Which version of FF are you using?

There is a tool for hunting regressions http://mozilla.github.io/mozregression/

But even without that, if you could roughly say which build is the first showing the issue.
about:buildconfig

Also in the "About Nightly" or "About Firefox" or so, it should tell the date, something like
52.0a1 (2016-11-09) (64-bit)

Comment 4

[George Roter]

51.0a2 (2016-11-09) (32-bit)

Here's the about:buildconfig page:

Comment 5

[Olli Pettay [:smaug][[e-mail]]]

Is that the first build showing bad performance? Older builds are faster?

Comment 6

[George Roter]

For sure it was good a few builds ago (not sure the exact one). But this one and the last one were bad performance, with the current one the worst.

Comment 7

[Olli Pettay [:smaug][[e-mail]]]

Well, could you look for the last good build? Since sounds like this is a regression, and for regressions we need regression range.

Comment 8

[David Bolter [:davidb] (NeedInfo me for attention)]

Mike, wondering if this bug is interesting (from a spinner perspective).

Comment 9

[Mike Conley (:mconley) (:⚙️)]

Hey groter - can you please post the text content from about:support in here? That'll give us some more clues about what we might be dealing with here.

Comment 10

[George Roter]

Sorry about the delay. Here ya go ... Google apps still more or less unusable.

Are you in Berlin office? If so perhaps ttaubert or someone could try to profile a bit where the issue is. (or you could use https://developer.mozilla.org/en-US/docs/Mozilla/Performance/Profiling_with_the_Built-in_Profiler )

[Desigan Chinniah [:cyberdees] [:dees] [London - GMT]]

:ttaubert — have you been able to connect with :groter? It would be super helpful to further profile the specific issue and provide more info for the team to move this along.

[Tim Taubert [:ttaubert] (inactive)]

Just talked to George and we'll try to sit down tomorrow and get a profile. I'll leave the ni? to remind me.

Comment 14

[Tim Taubert [:ttaubert] (inactive)]

Sorry, that took a while, but here are three profiles:

[1] https://cleopatra.io/#report=e1c0be0bc04890f4cd343339e39be4660d22b2f6
[2] https://cleopatra.io/#report=54786d5e45b4a90650f3ded2b2532f9307a98ed4
[3] https://cleopatra.io/#report=8574de95842dbf5ced2d1cda105480392492f139

In the first two I opened Google Slides, and loaded a slide show. Then switched between slides a little.

In the third I had an open slide show, switched between slides, added a new slide, removed it again.

[Olli Pettay [:smaug][[e-mail]]]

Hmm, that is the old  version of profiler, right? Any chance to install new one?

And which version of FF?

Comment 16

Do you have a link to the new version of the profiler?

Comment 17

[Olli Pettay [:smaug][[e-mail]]]

https://developer.mozilla.org/en-US/docs/Mozilla/Performance/Profiling_with_the_Built-in_Profiler has the link

Comment 18

[Olli Pettay [:smaug][[e-mail]]]

And could you possibly try Nightly.

Comment 19

[Olli Pettay [:smaug][[e-mail]]]

But as expected, mostly JS, also some painting.

Comment 20

[George Roter]

Still on Aurora for this one:

Looked at email, opened a Google Presentation, scrolled a bit:
https://perf-html.io/public/3e6b1a1ede0a8343066745f50b872187270d0cdc/calltree/?thread=2

Added a slide, deleted a slide, then moved to a GDoc and scrolled a bit and added a comment:
https://perfht.ml/2llg02h

Will try with Nightly.

George, any chance you can please share the presentation in that the profile in comment 21 is coming from?  In case it's not a public document, sharing it privately via email also works fine.  Thanks!

Comment 23

[George Roter]

Sorry I missed this.

I have no idea what document that was.

Would you like me to rerun the tests on a new document? I can do that later today (on my mobile now so not possible immediately).

Not really, just please keep this in mind in case you encounter slowness issues with Google Docs in the future.  We already have a lot of known slowness issues with Google Docs and it's extremely likely that the issue you're seeing is covered by one of those, but in case you encountered a doc in the future that happened to be particularly slow, please feel free to send it my way so I can have a look.  Thank you!
